结婚买钻不求人 教你读懂钻石GIA证书

       选钻石的时候被那张GIA证书弄得头晕眼花，有没有？看不懂上面的数据被店员忽悠地天昏地暗，有没有？我爱钻石网为你详解GIA证书上的玄机，让你5分钟读懂它，从此买钻不求人。

        首先先了解一下什么是GIA证书，GIA是Gemological Institute of America(美国宝石学院)的简称，是在公元1931年由Mr. Robert Shipley所创立，至今已有70几年的历史， GIA是非营利机构，经费由珠宝业界人士捐献，因为GIA不涉及营利事业，在名誉第一的前提之下，不会因人为因素影响鉴定结果、所以在鉴定书内容品质方面，极具公信力。 换句话说，GIA证书像钻石的身份证一样，记录了它的身份信息，也成为我们来挑选钻石的可靠依据。
